| Summary: | 碩士 === 國立虎尾科技大學 === 機械設計工程研究所 === 100 === The electric bicycle recent several years development is rapid, has provided one kind for the people facilely, the energy conservation, the environmental protection transportation vehicle. Electric cars resonance response is the reflection drives the personnel comfortable degree the target. In order to study the dynamic performance of electric bicycle frames, the nature frequencies and mode shape are analyzed by using ANSYS Workbench software. The frequency of the bicycle frame by using Experimental modal analysis, confirms the Theory modality analysis and the Experimental modality analyzes whether tallies, proves the bicycle frame finite element model the accuracy. Then joins the motor the exciting force to carry on the harmony response analysis, calculated the response of the bicycle frame in a certain frequency, obtains the response value and the frequency curve. Then, under the motor operation of the vehicle testing of measured spectrum, to determine the two analysis methods are consistent, using the finite element method for solving the natural frequency of the bicycle frame, to know whether under the motor rotation frequency close to resonance can be the first body of the dressing to avoid its resonance. The use of such methods hope that it can reduce development costs, reduce proofing time role.
